' Specification of Letters Patent. Application filed April 11, 1903. Serial No. 152,130.

- To all whom it may concern:

' Be it known that I, \VILnIAM Loni) Buss, a citizen of the United States, residing in the borough of Brooklyn, in the city of New York and State of New York, have invented newand useful IH'IPIOVQIXleHtS in Driving Mechanisms tor Axle-Dri ven' Dyna mos, of which the following is a specification. i

My-invention pertains to the lighting-of railroad cars by electricity generated by themotion of the same, and itsobject is to provide-a simple, reliable and flexible con-. nection between the axle of a railroad car and a hollow shaft surrounding and spaced from said axle and supported in bearings 'carried upon the truck Generating electricity by power takenfrom the axle of'a railroad car has been I undergoing development for many years and not given satisfactory service for several reasons. My invention of a. hollow shaft surrounding the axle and dru'en'by the 80 same, which I patented June 20, 1899, No.

627,291, gives excellent results in practice, and the present improvements relatemore particularly to "the means by which said axle and hollow shaft are connected.

Referring to the drawings, it will be seen the purposeof illustratingmne embodiment of the invention, consists of a two armed dog clamped upon the car axle and fourspecially constructed driving springs, which connect the endsof said dog to. two horns or crank-terms on the hollow shaft. The

.1 novel features of this construction, which I now desire to explain and patent, consist i45 Of thepeculiar construction of said driving 7 "springs and their method of engagement with the arms of the dog andhollow shaft. fgFigure 1 is an end elevation of the device, bile-Fig. 2 is a side elevation of the same.

- i lim Figsi 3- and filillustrate det-ails of the con- "struction of the springs. and the ball and socket faStenings withwhich they are fur Describing the'drawings, A is the axle of the car, B? and. B are the two arms of the dogwhich is clamped upon" said axle-by the bolts B 3, B and B.

. C and (.3 are the two symmetrical halves of the hollow shaft, provided with the two projecting arms or cranks ,G andC; The hollow shaft is supported in bearings'not shown, but which are illustrated in the patentreferred to. The hollow shaftis shown as broken oil", thefmissingportion' being an. extension, wl'iic'lrsupports a gear wheel or other power transmitting device. The

halves of the hollow shaft arefastened together by the boltsC and C". The ends of the arms of the dog are formed intojaws to receive and rigidly hold the double sockets D and D which are secured inpla'ce by the bolts 1) and 'D. The sockets E" and E are attached tO the horns or cranks CI and C by means of the bolts E and E. The said sockets D and D E and E consist of two similar halves and are provided with the spherical recesses F and l for the reception of the ball ended bolts to be described later. They'are more partimilarly shown in Fig. 3,-where said socket is illustratcd partly in'section- These halves are tightly closed and joined together by the bolts G G Gr and G, and when said sockets arein their-places at'the ends of the arms of the said dog and hollow' shaft, they are further cltised. and held firmly. togetliier by the bolts 1), D, E and-,E afore sail p H HEB and H are four ball ended helicalsprings, which connect "all of th said four sockets'together. Their construe ti'on'is more particularly illustrated in Figs.

3 and 4. Referring to -'-sanie"it will be seen that each ball ended spi'ingconsists of'the helical spring-H the twoends Otwhieh have been formed into the shape" of a cone to fit into the cups are provided with the. central aperture L, thewall of whichthreaded to receive the corresponding thread upon the shank ofthe ball ended bolt- 3". By this means said cup and bolt are firmly unite and become the base for one end of said helical 5 ring.

These last n'nmed members are. introduced ended bolts into the sp ei'ic'al recessesof'jthe "the arms C and C of'the hollow shaftby sion of this application, I have claimed the herein without reference to the purpose to which it is applied.

All tlia parts are interchangeable and easily adir'jsted. No lubrication is necessary or desirable. In operation, owing to the resiliency of the springs and the free play and motion afl'onled by theaction of the ball and socket joints, all joltings and other disturbing motions of the running car are neutralized and their effect dissipated, and the rotary motion only of the axle is transmitted to thclTollow shaft and its driving wheel, said driving wheel being enmeshed with a pinion upon the armature shaft.

In another application bearing-Serial No. 358,587 which is a divispring and its attaching means as set forth claimed as applied to a driving mechanism;

While the driving mechanism described in this specificationlis primarily intended to transmit power from .a car axle to ahollow may also be used in a reverse manner, that is when'the generator becomes a motor and is used for'propelling a car or vehicle. It may also be used in many applications, wherein it is necessary to transmit power between approximately concentric shafts desirable.
